Frequently asked questions

The time it will take to pay back your investment in solar panels will depend on several factors, such as the initial cost of the installation, the amount of solar energy produced, electricity prices and the tax and financial incentives available in your area.

In general, the payback time for the installation of solar panels is expected to be between 5 and 6 years, and there is a benefit on the electricity bill from the first day of installation.

The lifetime of solar panels depends on many factors, including the quality of the materials, the technology used in their manufacture, the amount of sunlight they are exposed to, the climate and the quality of the installation.

To install solar panels at home, you need:

  • Feasibility assessment to determine if your home is suitable for the installation of solar panels.
  • A solar panel system should be designed to meet the energy needs of your household.
  • Necessary permits must be obtained from the local government and comply with applicable rules and regulations.

To determine how many solar panels you need, you can make an estimate of your electricity consumption in a year and then divide that amount by the energy output of a single solar panel in your area. The energy output of a solar panel will depend on your geographical location and factors such as the orientation, angle and shade of your roof.

It is important to note that a solar panel system should generate enough energy to cover your home’s electricity consumption all year round.

With our system we calculate exactly how many solar panels your home needs and we draw up a quote adapted and exclusive to your case.
